TECHNICAL FIELD

The present application relates to the field of aerosol technologies, and in particular, to an aerosol fixing apparatus and an aerosol generating apparatus.

BACKGROUND

Microwave heating has advantages of high heating efficiency and rapid aerosol generation.
In the related art, an aerosol generating substrate is directly inserted into the bottom of a coaxial cavity. In this case, a microwave field near the top of a conductor column in the cavity is strong and can heat and fully carbonize the aerosol generating substrate in this part, while due to a weak microwave field in a part far away from the top of the conductor column, the aerosol generating substrate in this part is heated unevenly and is not completely carbonized, which loses significance of microwave heating and reduces utilization of the aerosol generating substrate.

SUMMARY

The present application aims to solve at least one of the technical problems existing in the prior art.
To this end, in a first aspect of the present application, an aerosol fixing apparatus is provided.
In a second aspect of the present application, an aerosol generating apparatus is provided.
The aerosol fixing apparatus provided in the first aspect of the present application includes: a mounting seat, the mounting seat including an atomizing cavity, the atomizing cavity being configured to place an aerosol generating substrate; a microwave introduction structure disposed on the mounting seat, an output end of the microwave introduction structure being located in the atomizing cavity; and a conductor member disposed on the mounting seat, at least a part of the conductor member being located on a side wall of the atomizing cavity.
The aerosol fixing apparatus provided in the present application includes the mounting seat, the microwave introduction structure, and the conductor member. The mounting seat includes the atomizing cavity. The atomizing cavity may be configured to mount and fix the aerosol generating substrate. Specifically, at least part of the aerosol generating substrate is located in the atomizing cavity and can generate aerosol when heated. In addition, the microwave introduction structure is disposed on the mounting seat, and the output end of the microwave introduction structure is located inside the atomizing cavity. The microwave introduction structure may be configured to introduce microwaves into the atomizing cavity to heat the aerosol generating substrate inside the atomizing cavity. Moreover, heating the aerosol generating substrate by microwaves can achieve rapid and efficient heating of the aerosol generating substrate, thereby improving generation efficiency and a generation speed of aerosol.
In particular, during the generation of aerosol, magnetic field intensity is strongest at the output end of the microwave introduction structure, and magnetic field intensity at other positions is weaker. Therefore, in the present application, the conductor member is disposed on the mounting seat, and at least a part of the conductor member is disposed on the side wall of the atomizing cavity. In this way, according to the present application, magnetic field distribution in the atomizing cavity can be changed by the conductor member, thereby achieving uniform heating of the aerosol generating substrate in the atomizing cavity. Moreover, in the present application, at least a part of the conductor member is required to be disposed only on the side wall of the atomizing cavity.
Specifically, during the generation of aerosol, there is a strong electromagnetic field near the output end of the microwave introduction structure, essence of interaction between microwaves and different substances is direct interaction between a microwave electromagnetic field and materials, and a high-frequency alternating electric field causes repeated polarization and violent movement of free or bound charges inside metal materials, which results in collision, friction, and internal friction between molecules, ultimately converting microwave energy into thermal energy. Therefore, in the present application, the conductor member is disposed on the mounting seat, the conductor member is a good conductor. During microwave heating, an eddy current in a surface layer of the conductor member may produce a skin effect and be concentrated on a surface of the conductor member, resulting in coupling with microwaves. The conductor member converts microwave energy into thermal energy, which can further effectively heat the aerosol generating substrate and ensure effective and uniform heating of the entire aerosol generating substrate.
Therefore, in the present application, the conductor member is disposed on the mounting seat, and at least a part of the conductor member is located on the side wall of the atomizing cavity. Then, changing a magnetic field distribution intensity in the atomizing cavity by the conductor member can ensure efficient heating of the aerosol generating substrate by microwaves, as well as ensure uniform heating of the aerosol generating substrate by microwaves.

To understand the above objectives, features, and advantages of the present application more clearly, the present application will be further described in detail below with reference to accompanying drawings and specific implementations. It should be noted that embodiment of the present application and the features in the embodiments may be combined with each other without conflict.

A first embodiment of the present application provides an aerosol fixing apparatus 100, which includes a mounting seat 102, a microwave introduction structure 106, and a conductor member 108.
As shown in FIG. 1, FIG. 2, and FIG. 3, the mounting seat 102 includes an atomizing cavity 104. The atomizing cavity 104 may be configured to mount and fix an aerosol generating substrate 300. Specifically, at least a part of the aerosol generating substrate 300 located in the atomizing cavity 104 can generate aerosol when heated. In addition, the microwave introduction structure 106 is disposed on the mounting seat 102, and an output end of the microwave introduction structure 106 is located inside the atomizing cavity 104. The microwave introduction structure 106 may be configured to introduce microwaves into the atomizing cavity 104, so as to heat the aerosol generating substrate 300 inside the atomizing cavity 104. Moreover, heating the aerosol generating substrate 300 by microwaves can achieve rapid and efficient heating of the aerosol generating substrate 300, thereby improving generation efficiency and a generation speed of aerosol.
In particular, during the generation of aerosol, magnetic field intensity is strongest at the output end of the microwave introduction structure 106, and magnetic field intensity at other positions is weaker. Therefore, as shown in FIG. 4 and FIG. 5, in the present application, a conductor member 108 is disposed on the mounting seat 102, and at least a part of the conductor member 108 is ensured to be disposed on a side wall 110 of the atomizing cavity 104. In this way, according to the present application, magnetic field distribution in the atomizing cavity 104 can be changed by the conductor member 108, thereby achieving uniform heating of the aerosol generating substrate 300 in the atomizing cavity 104.
Specifically, during the generation of aerosol, there is a strong electromagnetic field adjacent to the output end of the microwave introduction structure 106, essence of interaction between microwaves and different substances is direct interaction between a microwave electromagnetic field and materials, and a high-frequency alternating electric field causes repeated polarization and violent movement of free or bound charges inside metal materials, which results in collision, friction, and internal friction between molecules, ultimately converting microwave energy into thermal energy.

The conductor member 108 is a good conductor, during microwave heating, an eddy current in a surface layer of the conductor member 108 may be concentrated on a surface of the conductor member 108 by skin effect, resulting in coupling with microwaves. The conductor member 108 can convert microwave energy into thermal energy, which can further effectively heat the aerosol generating substrate 300 and ensure effective and uniform heating of the entire aerosol generating substrate 300.

In addition, in the height direction of the atomizing cavity 104, a ratio of a dimension of the conductor member 108 to a dimension of the aerosol generating substrate 300 is less than or equal to 1/3.
In this way, the dimension of the conductor member 108 is reasonably configured in the height direction of the atomizing cavity 104, such that the magnetic field intensity distribution in the atomizing cavity 104 is more reasonable, thereby improving uniform and efficient heating of the aerosol generating substrate 300 in the height direction of the atomizing cavity 104 by microwaves.

Specifically, the resonant column 206 can act as a conductor, and the resonant column 206 may be made of a metal material. Exemplarily, the resonant column 206 is made of copper, aluminum, iron, or alloys thereof. The resonant column 206 is configured to transmit microwaves and increase a microwave transmission rate. The microwaves are not prone to attenuation when conducted in the resonant cavity 204.
On the basis of the fifth embodiment and the sixth embodiment, further, the housing 202 may be a metal housing. In addition, the housing 202 may alternatively be a non-metal housing, and an inner wall of the housing 202 is provided with a second metal layer.
